Bausch & Lomb PureVision Contact Lenses
Advantages: Next best thing to perfect vision! Most hygenic option
Disadvantages: Can dry out sometimes, can be costly, not suitable for all
I have a fairly strong prescription (-7.50). I have been using Purvision continuous wear lenses for nearly 4 years now. I've been wearing contact lenses generally for around 17 years, gradually moving from pemanent soft lenses, to disposable monthlies, to the continuous wear. I find them absolutely fabulous.
I found that with non-disposable lenses my eyes were not getting enough oxygen and blood vessels started growing across my cornea. I also had higher calcium and protein deposits on my lenses than average. So I made the switch to monthly disposables, which sorted the problem out. When I decided to go on a 5 month backpacking trip through the middle east, I decided to look into continuous wear lenses for several reasons:
1. My vision is really bad, and I didn't fancy waking up in a hostel in the middle of the night and having to fumble for my glasses.
2. I didn't want to lug around 6 months' supply of cleaning gear, and didn't want to rely on being able to find it on the road.
3. I was worried about hygeine - I was not always going to have ready access to clean bathrooms to wash hands etc.
I therefore trialled a pair of Purevision lenses. According to my optometrist I am the best candidate she has ever seen for these lenses, so I am very lucky. If you have a tendency to dry eyes, you may not be suitable, or you may need to spend a small fortune on regular eye drops.
The lenses are specially developed to allow more oxygen to access the eye than standard soft contact lenses. Irrespective of the extended wear function, these lenses are actually the best for me because of this oxygen access. The continual wear is really just a bonus, but boy what a bonus!
According to their website these have:
" Special Performa™ surface treatment repels protein build-up, providing the most comfortable experience all through the day and night . PureVision contact lenses provide 4 to 5 times more oxygen to your cornea that conventional csoft lenses, greatly increasing comfort and freshness . Unique AerGel™ technology balances oxygen and water to provide all day/all night comfort"
I wear the lenses continually. I am supposed to take them out once a week for a few waking hours, but I have to confess I tend to forget. I try to make up for this by having periods of a week or two every couple of months where I do not wear them at all. I do take them out whenever I'm unwell at all, or if my eyes are feeling tired, which virtually never happens. What I do do fairly regularly is rub them with an all in one solution, which I find helps a lot, especially towards the end of the month.
I find these lenses incredibly comfortable. They are very thin, which means it can be difficult knowing whether they're inside out or not when putting them in. I think that if anything they're more comfortable than regular lenses, but I find all lenses comfortable, and unless I'm tired I can't feel them at all.
When first wearing Purevision you need to check in with your optician regularly so they can make sure that your eyes are suitable. When I first started wearing them, my eyes would be dry in the morning. The lens can stick to your cornea, but an eye drop or two sorts things out. As time goes by your eyes get used to the lenses and mine stopped drying out after a few weeks.
The joy of having perfect vision all the time is absolutely amazing. As someone who has had bad eyesight since early childhood, waking up and being able to see the time is wonderful.
I have had no problems with the lenses at all. One thing I do have to be careful about is knowing when you have an infection starting - I have had an infection a couple of times previously with other lenses, and you don't realise while you have the lens in. It is only when you remove the lens that you can feel the discomfort in your eye - the lens acts as a buffer. So, if you're not taking your lenses out, presumably there is a risk that you will not realise you have an infection developing. I am slightly paranoid about this, and will whip the lenses out if I have any concerns whatsoever, and more than once I've gone to the optometrist worried there's something wrong when everything has been fine. You just can't be too careful with your eyesight.
I had been considering laser surgery, but with the risks involved, I simply can't justify it. The lenses will cost more over a lifetime than the surgery would, but otherwise the benefits are virtually the same.
These are one of only 2 or 3 brands for continuous wear lenses. Ciba Vision do them, and I've noticed you can now get some own brand versions. I find that the Purevision are normally the cheapest anyway as I buy online, and being Baush & Lomb, it's a reputable brand. I have not tried the other brands, and don't know anything about them. I have simply stuck with my optometrist's recommendation.
The lenses can be expensive, although they're cheaper than dailies. Frankly I would pay a lot more for them, so I think they're excellent value for money.
Over the counter they can cost up to £30 a pair. It's far cheaper to buy over the internet - sites such as OKvision and Post Optics used to have the best prices, at around £12-15 a pair (for 6 months' supply), so between £70-85 for the full 6 months.
12 months' supplies are usually cheaper again, but my prescription has not yet stabilised so I don't buy that much at once. I've not yet made the leap myself, but buying internationally can be even cheaper.
However, Tesco.com have started selling contact lenses and Purevision are an amazing £8.74 a pair, which is just £26.22 for three months' supply, which is by far the cheapest I've ever seen them, plus you get the bonus of clubcard points etc.
Of course, whilst the lenses may not be the cheapest lenses around, you save on cleaning fluids. I just keep a small travel sized bottle of an all in one cleaner on me when I travel, and a big bottle at home, and that's all you need.
Now, a little secret - I cannot recommend doing this, but I have also been known to cheat (unintentionally) and wear them longer than 30 days. I am always forgetting when I started a new pair, and I'm sure I've gone over 5 weeks before, with no problems. I wouldn't recommend it and I'm sure the doctors and opthamologists out there are horrified, but nothing bad has happened to me (touch wood....).
I will never, ever go back to the other lenses. These lenses are way ahead of the others in so many ways - they are better for your eyes, because they allow more oxygen in, you can wear them 24 hours, you save on cleaning fluids, they are more hygenic because you're not handling them all the time, and you don't have to carry around lots of pairs the way you would with dailies.
Whilst medically they are not for everyone, I thoroughly recommend giving them a go.
